With a planned cleanup, using put_unaligned() on a single character
results in a harmless warning:
In file included from ./arch/x86/include/generated/asm/unaligned.h:1,
from include/linux/etherdevice.h:24,
from net/core/netpoll.c:18:
net/core/netpoll.c: In function 'netpoll_send_udp':
include/asm-generic/unaligned.h:23:9: error: 'packed' attribute ignored for field of type 'unsigned char' [-Werror=attributes]
net/core/netpoll.c:431:3: note: in expansion of macro 'put_unaligned'
431 | put_unaligned(0x60, (unsigned char *)ip6h);

Replace this with an open-coded pointer dereference.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
